Eliminate Render-Blocking CSS
Medium Impact+8 points estimated
Why It Matters
Critical CSS is blocking initial render and delaying both FCP and LCP by 150ms.
How to Fix
Extract above-the-fold CSS and inline it in the HTML head. Use Next.js CSS-in-JS solutions like styled-jsx or emotion for critical styles. Move non-critical CSS to load asynchronously using Next.js dynamic imports or the 'media' attribute trick.

AI Performance Analysis
This Next.js/React site has poor performance with a score of 69/100, indicating significant user experience issues. The biggest problem is an extremely slow Largest Contentful Paint of 6.0 seconds, primarily caused by a 3.8-second element render delay from an inefficient SVG image in the header. The site is also loading 73 KB of unused JavaScript code and using legacy JavaScript features that add unnecessary bloat, which could be eliminated by updating the build configuration to target modern browsers. Fixing the problematic header image, removing unused code, and addressing render-blocking CSS could potentially improve the performance score by 30+ points and drastically reduce page load times.
Other Optimization Recommendations
Fix Element Render Delay Issue
High Impact+25 points estimatedWhy It Matters:
Element render delay of 3.8 seconds is blocking LCP and causing the 6-second load time.
How to Fix:
The LCP element appears to be an SVG image with base64-encoded data. Convert this to an optimized static image file and use Next.js Image component. Remove the base64 encoding from the SVG mask and serve the image from a CDN. Consider using a smaller logo variant for faster initial render.
Remove Unused JavaScript Code
High Impact+15 points estimatedWhy It Matters:
73KB of unused JavaScript is delaying LCP by 450ms and increasing bundle size unnecessarily.
How to Fix:
Use Next.js bundle analyzer to identify unused code in chunks 9da6db1e and 9204. Implement dynamic imports for components that aren't immediately needed. Configure Next.js to target modern browsers only in next.config.js to remove legacy polyfills for Array.at, Object.hasOwn, etc.
